Wow this is going to be expensive then lol. I can get 360w 24v solar panels for £250. So based on them figures I would need 1800w of solar panels to be safe. Thats 5 panels. So £1250. Not that bad actually when I think of it.

I will be touring all across Europe most of the time. Canary Islands in the winter , mainland Europe in the summer so will have plenty of uninterrupted sunshine. I used the 30% reduction as was led to believe there would be a 30% loss in inefficiencies due to converting the power ? I wish I...

Yeah I understand that and was pretty much what I was trying to say. Getting a pure sine inverter to handle 840w will be easy. So I need to store 5169wh of energy. I will have 1000w solar panels so taking off the 30% due to inefficiency , that will only take just over 7hrs to store that , on a...

Its probably better if I break it down and explain. Ive based the figures on this.. <A> PC uses 750w and want to use it for 4 hrs a day (4hrs continuous) <B>Led Lighting are 2.8w each and I will have 10 of them all on for 8hrs a day continuous. <C> Water pump for the shower uses 30watts and...

Based on my estimated usage (gone overboard) I would use 3974w a day. Going the 24v route and getting 8x 3.2v 280ah batteries to make a 24v 280ah battery, that should be more than enough shouldn’t it? 280ahX24v is enough to power 6720w. Is that right? If so that’s the route I’m going to take as...

The bus is a 24v system but will be kept separate anyway from the solar and interior electrical load. 400ah on 12v is going to cost me £2000. If going 24v will mean I need less capacity than that then the 280ah will cost me approx £1000. Thats a big saving. Either route will cost me half by...

But going by my above post, going 24v, I will need half the amount of ah battery to have the same wh? If so then that’s quite a bit cheaper.

So if I was on a 24v system with 280ah I will have 6720wh and on a 12v system with 400ah I will have 4800wh so it’s still going to be better and cheaper for me to go 24v?

Confusing watts and watt hours? Been reading online the last few hours and think I am going to go the 24v route and get less battery ah as I’m right in thinking that a 12v system, the PC for example will use 250ah over 4hrs (750w/12v=62.5ah X 4hrs is 250ah) whereas a 24v system it will only use...

Anyone?

Also would lifepo4 be a better route for me , cost wise if I am wanting 400ah?

To clarify , the items that will be using electric are as follows. 12v LED Lighting spotlights in the roof Water Pump for the shower Charging the phones and tablet (using the original plugs connected to the inverter) Maxx Air fans PC (4hrs a day maximum as I am a video editor/colourist) The...

Hi All, Currently converting a Mercedes 814d bus to a motorhome and have a few questions. I have calculated that I will be using 3974w per day (that's going overboard with everything and also using a powerful PC which will pull 750w, 4hrs a day) and want to know if I've worked my calculations...
